LIQUID-STORAGE TANK.

Original application filed May 19,1322, Serial No. 562,107. Divided and this application filed February 1c, 1924. Serial No. 693,397.

To all whom it may concern: v

Be it known that I, J 01m H. VVIGGINS, a citizen of the United States, residing at Bartlesville, Oklahoma, have invented a certain new and. useful Improvement in Liquid-Storage Tanks, of which the following is a full, clear, and exact description,

- such as will enable others skilled in the tiled May 19, 1922.

art to which it appertains to make and use the same.

' .This invention relates to liquid storage tanks of the type in which the top or deck of the tank is not connected to the side wall of the tank, but normally floats upon and is supported by the liquid in the tank, any presentapplication-being a division of my application for patent Serial No. 562,107,

One'object of my present invention is to provide, a liquid storage tank that is equipped with an eflicient means of novel construction for sustaining'the deck whensaid deck is not supported by the liquid inthe tank.

Another object is to provide a novel means for bracing the side 'wall of a liquid storage tank against wind pressure.

Figure 1 ofthe drawings is a top plan view of a liquid storage tank constructed in accordance with my invention.

Figure 2 is a vertical transverse section- 211 view of said tank; and

Figures 3 and-4 are sectional views, illustrating certain details of construction of said tank.

Referring to the drawings, A designates a vertically-disposed, cylindrical member open at its upper end, that constitutes the side wall of the tank, B designates the bottom of the tank and C designates the top or deck of the tank which normally floats upon and is supported by the liquid in the tank. The sidewall of the tank is braced against wind pressure and maintained in circular shape by radially-disposed tension members B connected at their outer ends to vertically-disposed projections 1 on the side wall A and connected at their inner ends to a collar 2 onthe upper end of a verticallydisposed mast or upright 3 that projects upwardly from the bottom of the tank at the center of the tank, said tension members D being preferably provided with turn-buckles prefer. to equip the tank with removable hanger-rods 8 adapted to be arranged at the side wall'of the tank and at the center'of the tank and constructe 1n suc 1 a manner that they can be detachably connected to the deck, to the mast 3 and to the projections 1 at the upper edge of the sidewall A of the tank. For example, the hanger rods 8 adjacent the side wall of the tank can have their upper ends detachably connected to the projections 1 by removable U-bolts or other suitable devices 9 on the projections 1, as illustrated in Figure 3, and said hanger rods can be detachably connected at their lower ends to U-bolts orother suitable devices 10 arranged adjacent the periphery of the deck C, as shown in Figure 4. The hanger rods 8 at the center of the tank can be detachably connected at their upper ends to the collar 2 0n the mast 3 and detachably connected at their lower ends to devices on the center piece. or sleeve 7 of the deck up through which the mast 3 extends. The hanger rods can be equipped with turnbuckles or other suitable'devices for varying the length of said hanger rod. When the tank is emptythe deck can be sustained in a. horizontal position parallel to the bottom of the tank by means of the hanger rods 8, and when it is-desired to float the deck on the liquid in the tank, the hanger rods are disconnected from the deck and removed iron the tank.

The deck C is provided at its peripheral edge with annpwardly-projecting rim 11, and any suitable means can be used for closing the annular space between said rim and. the side wall of the tank, the means illustrated in Figure 4 for closing said space consisting of a shoe E arranged in slidin engagement with the side wall of the tank liquid in the tank is such as to cause the upper edge portion of the shoe E to project above the top edge of the side wall A of the tank, the upwardly-projecting devices 1 on said side wall to which the tension members D are connected serve as guides for the upper edge portion of the said shoe.

Havingthu's described my invention, what I claim as new and desire to secure by Letters Patent is:

1. A liquid storage tank provided with a side wall formed by a vertically-disposed, cylindrical member open at its upper end, a vertically-disposed mast or upright at the center of the tank, devices projecting upwardly above the top edge of said side wall,

radially-disposed tension member connected at their inner ends to sa d mast and at their outer ends to' said devices, and a floating deck supported by the liquid in the. tank and provided with a shoe whose upper edge portion slides upon-said upwardly-project- 1ng devices under certain conditions.

2. YA liquid storage tank, comprising a cylindrical side wall, a floating deck adapted to normally rest upon the liquid in the tank, a mast or upright at the center of the tank that projects upwardly through said deck, devices projecting upwardly from the top edge of the side wall of the tank, radiallydisposed tension members connected at their inner ends to said mast and at their outer ends to said upwardly-projecting devices, and a temporary sustaining means for the deck comprising hanger rods adapted to be arranged at the center and at the sidewalls of the tank and detachably connected at their ends to said mast and to the upwardly-projecting devices on the side Wall.
